Why roll threading? Thread rolling is the fastest and preferred method of economically producing smooth, precise threads of superior physical qualities. Our roll threading process produces a surface free of tears, chatters and cutter marks. Rolled surfaces have anti-galling properties and provide more contact area with mating parts. With added strength, the cost savings of efficiency and material maximization inherent to the process by which they are made, precision roll threaded products are the clear choice in a myriad of applications.
